Hi, if it is a 574 or 684, normally don't have to bleed the injection pump after changing fuel filters.
Here is my method for 684:
1)Run engine until up to normal operating temperature. Shut off.
2)Turn off fuel shut off valves at bottom of fuel tank.
3)Replace 1 or 2 fuel filters depending if your tractor has a 1 or 2 fuel filter system.
4)Open bleed screw on top of both fuel filters.
5)Open fuel shut off valves at bottom of fuel tank and wait for fuel to to come out of bleed screw on top of fuel filter closest to the fuel tank bubble free, then tighten bleed screw.
6)Repeat for next fuel filter if it is a 2 filter system.
7)Open throttle about 1/2, put Stop/Start/Run control lever to the Start position and start the engine. Engine may sputter and miss for a couple seconds then smooth out and then put Stop/Start/Run to Run position.

If engine fails to start then you will have to bleed injection pump and possibly crack an injector line.

Note: A small positive air pressure applied to the fuel tank will assist the bleeding process.
